Background
The fire extinguishing bottle is filled with 1211 fire extinguishing agent mixed with high-pressure nitrogen, and is typically applied to airplane systems and airplane engine short cabins for extinguishing sudden fire points in the engine short cabins and wing fuel tank cabins. When a sudden fire point appears in the nacelle, the electromagnetic switch of the fire-extinguishing bottle is opened, and the liquid fire-extinguishing agent is sprayed out through the valve and the nozzle under the action of high-pressure nitrogen. 1211 is heated and decomposed to generate bromide ions when it contacts with flame, and the bromide ions can combine with hydrogen radicals generated by combustion reaction to interrupt the chain reaction between hydrogen radicals and oxygen, so as to stop the combustion reaction and extinguish the flame, thereby achieving the purpose of extinguishing fire.
At present, manufacturers adopt a manual mixing and shaking mode in the fire extinguishing agent filling process. That is, after charging 1211 fire extinguishing agent of rated weight and nitrogen gas of rated pressure into the fire extinguishing bottle, in order to mix the two media sufficiently, the fire extinguishing bottle is held up manually, shaking in up and down or left and right directions is performed a plurality of times, the specific shaking speed and the number of times refer to the empirical value, after the shaking is finished, the weight of the fire extinguishing bottle (containing the fire extinguishing agent) is weighed on an electronic scale, the pressure in the fire extinguishing bottle is measured by a pressure gauge, and the quantitative constant pressure is corrected for a second time. This approach is abbreviated as: experience guide, manual operation, weighing (pressure measurement) verification, charging under the condition of insufficient charge, discharging under the condition of overhigh charge, and circulating operation until the operation is qualified.

Workstation 4 is the flat structure, the lower extreme of workstation 4 is located to clamp 2, just clamp 2 with workstation 4 is perpendicular. The clamp 2 adopts a locking manner (not shown, being a finished component) to vertically fix the fire-extinguishing bottle 1 on the workbench 4. The fire extinguishing bottle 1 is vertically arranged after being installed and is parallel to the workbench 4. The sliding rail assembly 7 comprises a linear guide rail (not numbered) and a sliding block (not numbered) matched with the linear guide rail, and the sliding block is fixed on one side of the workbench 4, which is far away from the fire extinguishing bottle 4; the side of the linear guide rail away from the slide block is fixed on a rack (not shown).

In the present embodiment, the output shaft of the reduction motor 3 is an eccentric shaft.
The rotary motion of the output shaft of the speed reducing motor 3 is converted into the up-and-down circular vibration of the upper end (hinged end with the working platform 4) of the connecting rod 9. The oscillation stroke is determined primarily by the length of the rocker arm 10, and is proportional to the length of the rocker arm 10. The driving force is mainly determined by the power of the reduction motor 3, and is proportional to the power of the reduction motor 3.
The reduction motor 3 has a frequency converter. The motion principle of the driving mechanism is that the speed reducing motor 3 always rotates towards one direction (both positive rotation and negative rotation) to complete the up-and-down circulation action of the vibrating mechanism, and the frequency of current is changed by the frequency converter to control the rotating speed of the motor, so that the functions of fast and slow speed regulation of the vibrating table are realized.

The weight measured by the load cell 5 is the total weight of all the components including the vibration mechanism, and 1211 represents the weight of the extinguishing agent filled in the vibration mechanism as the total weight — the weight of the extinguishing bottle body.
In the vibration process, the piston rod of the electric cylinder 6 is withdrawn downwards to drive the weighing sensor 5 fixedly connected with the piston rod to move downwards together, the upper end face of the weighing sensor 5 is separated from the lower end of the working plate 4 to be contacted, and the upper end face of the weighing sensor 5 is positioned outside the vibration stroke of the working table 4 until the upper end face of the weighing sensor 5 is positioned, so that the weighing sensor 5 cannot generate limit or interference in the vibration process of the working table 4.
